296 to GTX327 and SL40

[ao.frog]

Hi.

I've the Garmin 296 Map and the SL-40, and to have the 296 auto tune freq's into the standby window would be REALLY nice!

I've downloaded the above mentioned schematic (what a pro-looking diagram!) but can't find that connector on my 296??

On the back of my 296, there's the powerwire which is going into the "sigarette outlet" for charging, the antenna connector, the 5-pin connector which is for updating the software... and that's it....

Where's the 9-pin connector mentioned in the diagram...??

Am I blind, stupid or possibly both??

You need to buy the Garmin accessory harness. It plugs in just like the 12v power wire but has the othewire you need to download to the SL-40.

If you want to gamble it might be the same harness as your 12v power wire if you cut the adapter plug off.

Maybe someone else has done this already and knows for sure.

I don't know this first-hand, but I was told by a usually reliable Garmin guy that if you cut the cigar lighter end off, you won't find anything but the power wires.....might not be a good gamble! we bought the accessory cable when we wired up Louise's plane last year.

The power/data connector on the back of the 296 is the 9-pin connector.

The cable you want is this one: https://buy.garmin.com/shop/shop.do?pID=1083

Thanks for all the good advices guys!
I'll contact Garmin and order the cable.

I didn't have a clue that the SL-40 and the 296 could talk together, since my 296 didn't have a cable to connect to other avionics, but now I'm starting to look forward to that nice "dial-in standby freq feature. :-)

I'm learning something new EVERY day since I started this building process... great!

And this forum really is great too!

I can confirm that it does not have the extra wires in there! I cut mine trying to gain access to the speaker outputs to prevent purchasing the cord with the speaker in there.

The only wires in the standard power cord are the power wires!
